Traction-wheel.



l G. B. LORD. TRAGTION WHEEL. APPLOATION FILED 1153.27, 1911.

` To all fir/wm i'f 'nii/,y concern citizen of the. United States,`anila l. Loin). a resident of the city of St. Louis and Stateof Missouri, have invented a new and useful linpro-yeinent in Vlraction-Wheels. the following a specification'.

This invention relates to traction wheels lle it known thatLCnics'riin i and it has for its -princ'ipal objects to 'secure j hereinafter described and claimed. v

like symbols refer considerable ti-active force without tearing up or mari-ing the surface of roads, to pro j duce a wheel which will travel easily over softnor muddy ground.I and to attain `certain other advantages which' will hereinafter more fully appear.

The invention consists in the parts and. in

the arrangements and combinations of parts In the accompanying drawing which Vforms part of this specification and Vwherein to like parts" wherever they occi1r,.Figure 'l is anvend View partly in elevation and partly in sect-ion; and VFig.

2 is a side View partly in elevation and partly in section. y j

The wheel comprises a middle'member,z and` preferably rigidl and `formed iiitegrally; having a web l and an annular iiange portion 2 distributed equally on opposite sides.y

of said web 1.v The central portion of the web or body l is raised or taperethas at 5%. on its opposite sides adjacent to tlie respective hub portions 4.

Extending transversely across the circumferential face of -the flange portion 2A are a series These cleats or members 5 have flattened outer faces so that the wheel is provided `the ange Q;

with a polygonal tread surface. Thecleats are spaced apart eqiiidistant and preterably bolted 4to the flange port-ion Q by bolts l (3 whose'heads are ciniiitersunk into depressions or counter-bores? in t-he outer faces Iof vthe respective cleats. Preferably, the

cleats 5 are extended beyond the edges of y and secured tothe end por tions of ythe cleats are metal rings S .which are preferably rigidvand angular' in cross section as shown. j These rings respective cleats 5 by bolts 9 whose 4heads yare preferably countersunk into" the cleats in a man-ner similar to the bolts 6'. By

arranging the cleats 5 so as to change the tiead of the wheel from round to polygo-` nal shape considerable tractive force is ob-4 spcification gf Leiters raient.' Application filed February of which.

of theirdestriictive effect on the roadway. UAlso` by the present construction the wheel will trayelwithoiit slipping on muddy and softened ground; 21nd,' owingto the spaced arrangenient.v of :the cleats, the corners thereof cling to the surface ofthe .roadway or ground without any 4-material destructive effect. So, too, the `arrangeinentof the hub portion ofthe wlieelis siiehthat any mud or dirt that is pressed in between the cleats will nottind lodgmentj but will be deflectwing to its peculiar gement of the outside shape. `By" `the i rings 8,?.tl1e` projecting ends of the cleats are "fastenedindependently of. the flange porvt-1on\2,"f.nd the 'strains are distributed equally on all the 'cleats.` This arrangement :alsofpermits of using a standard intermediate supporting portionofa common Width and set-.tiring thereon bars or cleats of vari 4cus lengths` i i g Obviously, thefu'lieeladmits of considerable fmoditcation without departing troni my invention. Therefore, I do not wish to 'be limitedjltofthe specific construction and arrangenient show vvn. `l`lVhatpI claimfis; l v

`15A traction wheel comprising a rigid `metal riin", li-multiplicity of cleats secured transversely on the circiiinferential face of said metal rim, said cleats being spaced an equal distance apart and their end portions being extended beyond the edges ot said metal rimpand rings connecting the end 'portions of said cleats, said rings being` spaced from said metal rim. 2. .A traction wheel comprising a siip` porting ring, a multiplicity of'tlat wooden tial face on said supporting i'ingso as to presenta polygonal tread face, said cleats being `spaced equidistant and extending on opposite sides of said siil'iporting ring, and rigid ring members connecting the end poi-- tions of.said cleats. said ring members bef ing spaced' from said supporting ring.

A tractionxwheel comprising an aniiu- -lar middle supporting member, a multiplicity of cleats se'cured'transversely across the peripheral face of'said annular middle siip' porting member and extending on opposite sidesr of the latter, `and L-shape annular members whose horizontal flanges extend cleats rigidly secured to the circumfereninwardlyl'andlare secured to the adjacent end portions of said cleats and whose vertical anges extend outwardly and abut the ends of the cleats, said Lshaped annular members being spaced Yfrom said annular tantially cylindrical rim portion, a' mul- -tiplicity of cleats disposed. transversely Iacross the circumferential faceof said rim and projecting beyond the edge thereof a considerable lrelative distance, and a rigid annular floating member separated from said rigid supporting member and secured to 15 the rojecting end portions of said cleats.
